Jacob’s Story – Sharing Internet Connections with Neighbours

Sharing Internet Connections with a Wireless Bridge
by    Jacob Johnson

This document shows three different examples of how an enterprising BIRRR member has helped himself and others share internet connections via a WIFI link.

I have a fixed wireless connection and share to my neighbour who had a failed install 300m away through some thick trees. I also set up the same system between another two neighbours in the same situation. My speeds are slightly affected but only because we are sharing a single connection.  We did this because it was cheaper that way.  My neighbours don’t download anything just watch Netflix occassionally. The nbn NTD can support up to 75mbit so it is not a problem if both properties are on the 25/5 plans but you may experience slightly slower speeds if both were on a 50/20 plan downloading full speed.

  1.  A 300m 2.4Ghz WIFI link – nbn FIXED WIRELESS

A newly installed nbn™ Fixed Wireless ODU with a Ubiquiti Nanostation attached to the Fixed Wireless mast.

MY HOUSE: This was originally a temporary mount for the Nanostation, but it appears to work perfectly with no interference; so it may stay! It is directed to the ‘clothes line’ Ubiquiti Nanostation shown below.

The picture above shows a newly installed nbn™ Fixed Wireless ODU and a Ubiquiti Nanostation attached to the Fixed Wireless mast. The Ubiquiti nanostation is used to transmit the Fixed Wireless connection over WIFI from this location

The Nanostation WIFI link connects to the ‘clothes line’ Ubiquiti Nanostation shown below.

The clothes line Ubiquiti is connected via Ubiquiti tough cable running through a conduit to home.

NEIGHBOUR 1:

The clothes line Ubiquiti is connected via Ubiquiti tough LAN cable via underground conduit, to the home. The home roof was not suitable for the WIFI link as it had too many trees in the signal path and the clothes line was a cheap pole on which to mount the Nanostation.

The 2.4Ghz link is ~ 300m and the wireless receive signal level is 63dbm. That is an excellent result.

 

2.  A 350m 2.4Ghz WIFI link – nbn FIXED WIRELESS

NEIGHBOURS 2 & 3:

The next two photos show a link which shares fixed wireless between two of my neighbours. It passes through a grove of trees, but the signal is perfect. The house roof ones aren’t solar powered, a cat5 cable runs down into the house, into the poe port of the Ubiquiti power injector.

The 2.4Ghz link distance is ~ 350m and the receive signal level is 65dbm.

An excellent result.

3.  A solar powered 3G Installation and 2.5Km 5Ghz WIFI link – MOBILE BROADBAND

This WIFI link delivers internet from a solar powered 3G modem and router installed on an elevated ridge. Internet is beamed down to a site that has no mobile reception via a WIFI link.

The 5Ghz link is ~ 2.5km and the receive level is 60dbm.
